Theoretical and Experimental Investigation of Barrier-Energy-Dependent Charge Injection Mechanisms in Organic Photodetectors (Adv. Funct. Mater. 2/2023)

Abstract

Organic Photodetectors

In article number 2209615, Nguyen, Wang and co-workers investigate the thermionic emission and tunneling models to identify the origin of experimentally observed dark current in an organic photodetector. By elucidating the dominant mechanism that induces dark current, an effective organic photodetector is developed. This experimental and theoretical exploration of dark current accelerate commercialization of organic photodetectors by suppressing noise.
